“Aunt Lizzie’s family” written on the back. According to Judy Majdanski (great granddaughter of Anna Bush), these pictures are of Lizzie Bush Wiersema and includes her sons Harry, George, possibly Richard and daughter Gertie. Thank you, Judy!
This looks like George Wiersema with John Roetman and Hattie Apsey. Hattie and George were cousins.
